There are down days why you get on the internet and look up survival statistics and you wonder. Reporter: They walk the pan mass bridge. It wasn't until my second to last chemotherapy treatment i walked over the bridge and stopped and started looking at the pictures and I said to my wife I'm going ride that. Reporter: Which is exactly what he did the very next year pedaling the 168-mile route with his daughter and sara cheering him on both finally in remission. I continued to volunteer and I was like why am I not riding it with him. We fought cancer together and now giving back together. Reporter: This is their fifth and they'll ride the 190 miles with a new purpose, her daughter fiona. I don't want there to be cancer when she's 21 years old. I want it to be something of the past.
